SMA Sunny Boy 3.8-US 3800W Grid Tie Inverter

The SMA "-41" Series Sunny Boy inverter, featuring SunSpec signal transmitter chip, is one of the most versatile residential inverters available. Combine this series with the SMA-TS4-R-F in order to build cost effective NEC 2017 PV RSS compliant string systems, or pair with SMA-TS4-R "-S" / "-O" (and comms gateway) to provide module level monitoring / optimization (respectively). Or leave all the rooftop electronics behind and design the system to take full advantage of the Secure Power Supply (SPS feature not Compatible with Sunspec based PV RSS). 600V max system DCV, compatible with both 240V and 208V sites, and backed by SMA's Power+ customer service package.
